'Triggering Buttons between Forms

Q.  I`m trying to write some code where clicking a radio button on form #1 makes 
a command button visible on form #2. I know how to do this within one form, but 
I don`t know how to do this with two forms. 

A. This is an easy one. You just have to include Form2`s name in front of the 
button`s name. Example:

1.)Create two forms(Form1 and Form2)
2.)On Form1 place two option buttons(Option1 and Option2)
3.)On Form2 place one command button(Command1)

'code for Form1
Private Sub Form_Load()
  Form2.Show                       'Show Form2 along w/Form1
End Sub

Private Sub Option1_Click
  Form2.Command1.visible = True    'Show button. See?
End Sub

Private Sub Option2_Click
  Form2.Command1.Visible = False   'Hide button.
End Sub
